I 100% agree but in this case its been 6 full years without leaking

Sounds like you don't agree 100%.

We're just offering possibilities. It's actually more interesting to some of us that the fitting was 3/4 turn loose and did not leak sooner.

If it was mine I'd pull that line and make sure I didn't need more parts before starting the MC replacement. Might find out that you don't need a new MC, you actually need a new hard line.

Or a new flare on that tube and maybe a new flare nut. I'd venture a guess that it didn't go 6 years without any leak at all - probably just one that was slight and unnoticed... (just like many plumbing leaks)

that makes sense

Update for all of you. We very may be in business here and you were all right - the hydraulic line was crooked/not fully seated and once I took it out and reseated it, the leak was gone. Again, I still don't understand how it didn't leak over the course of 6 years and thousands of miles, but I guess that was a good thing. I am going to bleed the brakes tomorrow just to be safe but I did bleed the master after all of this and the pedal feels good.

Here are pictures of the line screwed in before, the flange/nut's condition when I took it out this evening, and how the cylinder looks now with the line in straight.
